HMRC Is Coming for Your Crypto: What the 2026 Reporting Changes Mean for You
From 1 January 2026, HMRC will gain direct access to data held by UK-based crypto platforms — including exchanges, wallet providers, brokers, and NFT marketplaces. This is a major shift in how crypto activity is tracked, taxed, and enforced.
These changes come as part of the UK’s adoption of the OECD’s Crypto-Asset Reporting Framework (CARF) — an international effort to bring transparency to the crypto space and combat tax evasion across borders.
If you use, trade, or invest in crypto assets, here’s what you need to know.

What Is the Crypto-Asset Reporting Framework (CARF)?
CARF is a global standard introduced by the Organisation for Economic Co-operation and Development (OECD). Its goal is to make crypto transactions more transparent to tax authorities, similar to how banks already report interest and dividend income.
The UK has committed to implementing CARF starting in 2026. Dozens of other countries are following suit.

Who Will Be Affected?
These new rules apply to:
- All UK-based cryptoasset service providers, including:
- Crypto exchanges (centralised and decentralised)
- Brokers and trading platforms
- Custodians and wallet apps
- NFT marketplaces
- Anyone using those services who is a UK tax resident (or resident in another country that adopts CARF).
---
What Will Be Collected and Reported?
From 1 January 2026, crypto platforms will be legally required to:
- Collect customer details:
- Full name
- Date of birth
- Residential address
- Taxpayer Identification Number (such as your National Insurance number or UTR)
- Track and report every transaction:
- Type of crypto asset
- Nature of transaction (buy/sell/send/receive)
- Date and time
- Number of units
- Value in fiat currency
- Provide annual reports to both HMRC and the user by:
- 31 January 2027 (user notification)
- 31 May 2027 (submission to HMRC)
This data will cover the entire 2026 calendar year.
---
What If Platforms Fail to Comply?
Failure to collect or submit accurate data can result in significant penalties:
- Up to £300 per affected user
- Additional fines for repeated or deliberate breaches
This creates strong incentives for platforms to over-report rather than under-report — meaning more scrutiny, not less.
---
Why This Matters
Until now, crypto has operated in a regulatory grey zone. While gains and income have always been taxable, enforcement has been limited by the lack of reliable data.
With CARF, HMRC will have real-time access to your crypto transactions. This will help them:
- Track capital gains from disposals
- Identify income events like staking, mining, or airdrops
- Spot patterns of evasion or underreporting
In short: if you trade, earn, or hold crypto, HMRC will now know — and they’ll expect your tax returns to reflect it.

What Should You Do Now?
1. Get your records in order
If you’ve been trading without tracking, now is the time to start. You’ll need accurate records of every transaction going back at least to January 2026 — ideally longer.
2. Choose an accountant who understands crypto
Crypto tax is complex. There are rules around:
- When a token swap is taxable
- Whether staking rewards count as income or capital
- How to claim losses for coins that became worthless
- And how to handle forks, airdrops, and bridging chains
Most accountants aren’t trained in this. But HMRC is watching.
3. Be proactive
This isn’t about fear — it’s about preparation. With the right support and record-keeping, you can stay compliant, claim all your allowances, and reduce your tax bill legally.

Conclusion
The 2026 reporting changes mark a new chapter for crypto in the UK. Transparency is coming — fast.
Make sure you’re ready.
If you trade, invest, or earn income through crypto, now is the time to tighten up your tax position and work with an adviser who understands the space.
